The bulb is then charged with a suitable solution, such as a bicarbonate of soda solution, and applied as explained in connection with the water, in order that the nasal passage and sinuses may be douched. The device 1s then withdrawn and as a similar treatment is desirable to inject by the same method, a warm solution of some antiseptic, such as a chlorine solution. It has been found through the treatment of a large number of dogs that the device is most effective as the treatments can be eifr ciently made with facility and ease andwithout subjecting the animal to any pain through undue pressure of the appliance on the muz- 5 zle. It will be understood of course that it is possible to slightly modify the device within the spirit and scope of the appended claim.

I claim:

A nozzle for canine nasal irrigators of generally conical form and having a stem cornmunicating therewith and projecting from the apex thereof, the side portions of the nozzle being bowed forward relative to the top portions thereof but at a sharper or more receding angle at the bottom than at the top, the front end of the nozzle chamber being flared relative to the chamber proper; the lower portion of the front end of the nozzle being substantially horizontal and the upper portion of said end of relatively pointed or upwardly tapering form.

In testimony whereof I afiix my signature.
